Although these EV devices can make HMI design much easier, they may necessitate additional engineering work. It is recommended to optimize the design when it has a relatively complex structure on more automotive equipment, as this may lead to potential defects. Here are a few pointers to help you fine-tune your performance:
Set PCLK to the smallest value permitted by the square LCD panel so that the GPU can process more lines per second.
Gradually increase the horizontal blanking time while keeping the vertical blanking time within the LCD manufacturer panel's time limit.
It will be very wise to use an efficient synchronization function. In the maximum PCLK cycle in the square LCD display specification, the maximum energy recession for synchronization can be defined in this way.
Always check for graphics errors visually, or use error flags to ensure that graphics aren't missing. If there is an underrun, export the line time to determine which line/area is underrun, and then optimize the display list accordingly--for example, by replacing the pointer with a solid line or by using an image instead of small numbers to cover a few windows in the same area.
For Unicode fonts, RAM_G's font correction can be used.
Load the ASTC image into RAM_G and watch the animation from there.
Touch controllers from direct suppliers can use the BT817, which supports capacitive touch operation (BT88888888 supports search-based touch HMI). Custom touch buttons are created by the C compiler and loaded into the BT817 during runtime. Alternatively, you can use the touch host mode to read touch data from the CTP via the MCU and write it back to the BT817 for TAG operation.
When a 3-point demonstration program is required, the touch screen typically executes it at a predetermined screen position. Some strip LCD screens are created by cutting standard LCD glass into strips. Take a 1280 x 800 LCD glass and cut a 1200 x 280 LCD out of it. This is displayed on the stretched LCD by the default restore procedure. Engineers can use the display function on the BT817 to define the position of three points. to achieve
The EVE equipment from Bridgetek is provided. As a result, the ground display point's HMI implementation will start up and respond faster, as well as provide better graphics performance. BT817/8 can work with a variety of MCUs as long as they have an SPI interface. Bridgetek provides a support tool chain, as well as sample applications and detailed engineering instructions, to assist designers in getting up and running quickly and providing ongoing support throughout the application design process.
